Tax Lookup and Appeals Tool
Determine your parcel tax and request appeal
The Safe, Clean Water Program is funded by a tax on private properties that contribute to stormwater pollution. The Program helps property owners understand how they are taxed, how they can become eligible for exemptions, reductions, or credits, and how they can appeal.
The tax is calculated for each applicable parcel based upon the parcel’s impermeable area (think buildings, roofs, driveways, sidewalks, sheds, and pools) as determined by the County Landcover Survey (or other applicable tool). The Chief Engineer may periodically initiate an update to the County Landcover Survey and periodically re-evaluate the characteristics of parcels to ensure accuracy of tax calculations.
The Safe Clean Water Program’s Landcover Survey was updated for Fiscal Year 2025-2026. This Landcover Survey provides the aerial imagery used to calculate your parcel’s Safe Clean Water Tax. Although the tax rate (2.5 cents per square foot of impermeable area) has not changed, your parcel’s impermeable area may have changed. Please refer to your FY 25-26 Los Angeles County Annual Property Tax Bill to see your own parcel tax amount. Each parcel’s impermeable area – as determined by the latest Landcover Survey – is anticipated to remain in effect until the next Landcover Survey update, approximately once every three years.
If you believe there is an error in your Safe Clean Water Tax, you may appeal using the online Appeals Tool at: https://apps.gis.lacounty.gov/bos/m/?viewer=SafeCleanWaterAppeal. Please note that appeals determined to be valid are only valid until the next Landcover Survey update.

Property owners who demonstrate stormwater improvements that result in water quality benefits, water supply benefits, and community investment benefits are eligible for the credit program.
Property owners exempt from the Safe Clean Water assessment (Qualified Seller) and demonstrate stormwater improvements that result in water quality benefits, water supply benefits, and community investment benefits may be eligible for the Credit Trading Program.
These Qualified Sellers may generate Tax Credit Trading Units (TCTUs) to sell to parcels subject to the Safe Clean Water assessment (Qualified Buyers). These TCTUs are purchased at a price of less than $1 per TCTU and each TCTU represents $1 applied to the Qualified Buyer’s Safe Clean Water assessment. TCTU transactions must take place within BOTH the same watershed area and municipality. Look up your parcel’s watershed area HERE.
Qualified Sellers looking to generate TCTUs shall submit their application and Engineer’s Report to the Online Application and Recertification.
Qualified Buyers shall contact safecleanwaterla@dpw.lacounty.gov or 833-275-7297 for available volumes of TCTUs and for the Qualified Seller’s contact information.
The Qualified Seller and Qualified Buyer shall negotiate and agree to a price per TCTU (at less than $1 per TCTU) and submit a Purchase Agreement and Purchase Receipt to safecleanwaterla@dpw.lacounty.gov for Public Works review and approval. If approved, the TCTUs are deducted from the Qualified Seller and applied to the Qualified Buyer Parcel’s Safe Clean Water assessment.
It should be noted that apart from the required information specified in these Credit Trading Program Transaction Guidelines, Public Works staff does not provide the format or other content of the Purchase Agreement. The format and any other Purchase Agreement provisions deemed necessary are up to the discretion of the Qualified Buyer and Qualified Seller so long as the Purchase Agreement (and Purchase Receipt) otherwise comply with these Credit Trading Program Transaction Guidelines. The Qualified Buyer and Qualified Seller should satisfy themselves as to the Purchase Agreement’s and any other related documents’ sufficiency, including from a business and legal standpoint, as Public Works staff is not responsible for making such determinations on behalf of the Qualified Buyer and Qualified Seller.
Options for exemption:
Low-income senior property owners may apply annually for an exemption from this special parcel tax. In order to qualify, the applicant must be 62 years of age or older, reside in a single-family residence, be the sole maintainer of the home, and qualify as a low-income household, as determined annually by the California Department of Housing and Community Development.
Parcels that are exempt from ad valorem property taxes are also exempt from this special parcel tax. This includes qualifying non-profit organizations and other exempt properties. This exemption will be automatically applied to the tax bill with no action required of the property owner.
Options for reduction:
Through the General Income-based Tax Reduction Program, very low-income and extremely low-income household parcel owners may receive a reduction from the special parcel tax. Qualified households will receive a reduction percentage based on the household income and number of persons in the household.
